CentOS7下编译安装ffmpeg3.1.5
一、安装依赖包
# yum -y install gcc glibc glibc-devel make nasm pkgconfig lib-devel openssl-devel expat-devel gettext-devel libtool mhash.x86_64 perl-Digest-SHA1.x86_64
二、编译依赖包
zlib-1.2.8.tar.gz
# tar-xzvf zlib-1.2.8.tar.gz
# cd zlib-1.2.8
# ./configure
# make
#make install
# cd ..
pcre-8.12.tar.gz
# tar -xzvf pcre-8.12.tar.gz
# cd pcre-8.12
# ./configure
# make
#make install
# cd ..
yamdi-1.4.tar.gz
# tar -xzvf yamdi-1.4.tar.gz
# cd yamdi-1.4
# make
#make install
#cd ..
yasm-1.3.0.tar.gz
# tar -xzvf yasm-1.3.0.tar.gz
# cd yasm-1.3.0
# ./configure
# make
#make install
#cd ..
faac-1.28.tar.gz
# tar -xzvf faac-1.28.tar.gz
# cd faac-1.28
#make
#make install
在make是出现错误mpeg4ip.h:126:58: 错误：对‘char* strcasestr(const char*, const char*)’的新声明
char *strcasestr(const char *haystack, const char *needle);
^
In file included from mpeg4ip.h:107:0,
from mp4common.h:29,
from 3gp.cpp:28:
/usr/include/string.h:365:26: 错误：使旧的声明‘const char* strcasestr(const char*, const char*)’出现歧义
extern "C++" const char *strcasestr (const char *__haystack,
make[3]: *** [3gp.o] 错误 1
make[3]: 离开目录“/usr/local/src/myffmpeg/faac-1.28/common/mp4v2”
make[2]: *** [all-recursive] 错误 1
make[2]: 离开目录“/usr/local/src/myffmpeg/faac-1.28/common”
make[1]: *** [all-recursive] 错误 1
make[1]: 离开目录“/usr/local/src/myffmpeg/faac-1.28”
make: *** [all] 错误 2
解决方式为：
修改faac-1.28/common/mp4v2下的文件mpeg4ip.h
从123行开始修改到129行结束。
修改前：
#ifdef __cplusplus
extern "C" {
#endif
char *strcasestr(const char *haystack, const char *needle);
#ifdef __cplusplus
}
#endif
修改后：
#ifdef __cplusplus
extern "C++" {
#endif
const char *strcasestr(const char *haystack, const char *needle);
#ifdef __cplusplus
}
#endif
faad2-2.7.tar.gz
# tar -xzvf faad2-2.7.tar.gz
#cd faad2-2.7
# make
#make install
#cd ..
lame-3.99.5.tar.gz
# tar -xzvf lame-3.99.5.tar.gz
# cd lame-3.99.5
#./configure --enable-nasm
# make
# make install
# cd ..
libogg-1.3.2.tar.gz
# tar -xzvf libogg-1.3.2.tar.gz
# cd libogg-1.3.2
# ./configure
# make
# make install
# cd ..
libvorbis-1.3.5.tar.gz
# tar -xzvf libvorbis-1.3.5.tar.gz
# cd libvorbis-1.3.5
# ./configure
# make
# make install

libvpx-1.5.0.tar
# tar -xf libvpx-1.5.0.tar
# cd libvpx-1.5.0
# ./configure --enable-shared
# make
# make install
# cd ..
SDL-1.2.15.tar.gz
# tar -xzvf SDL-1.2.15.tar.gz
# cd SDL-1.2.15
# make
# make install
# cd ..
在make是出现错误：
./src/video/x11/SDL_x11sym.h:168:17: 错误：与‘_XData32’类型冲突
SDL_X11_SYM(int,_XData32,(Display *dpy,register long *data,unsigned len),(dpy,data,len),return)
^
./src/video/x11/SDL_x11dyn.c:95:5: 附注：in definition of macro ‘SDL_X11_SYM’
rc fn params { ret p##fn args ; }
^
In file included from ./src/video/x11/SDL_x11dyn.h:34:0,

^
make: *** [build/SDL_x11dyn.lo] 错误 1
解决方法为：
修改文件./src/video/x11/SDL_x11sym.h
将168行
SDL_X11_SYM(int,_XData32,(Display *dpy,register long *data,unsigned len),(dpy,data,len),return)
修改为
SDL_X11_SYM(int,_XData32,(Display *dpy,register _Xconst long *data,unsigned len),(dpy,data,len),return)
x264
# cd x264/
# ./configure --enable-shared
# make
# make install
# cd ..
xvidcore-1.3.4.tar.gz
# tar -xzvf xvidcore-1.3.4.tar.gz
# cd xvidcore/build/generic
# ./configure
# make
# make install
# cd ../..
# cd ..
三、安装ffmpeg3.1.5
ffmpeg-3.1.5.tar
# tar -xf ffmpeg-3.1.5.tar
# cd ffmpeg-3.1.5
# ./configure --prefix=/usr/local/ffmpeg/ --enable-version3 --enable-libvpx --enable-libfaac --enable-libmp3lame --enable-libvorbis --enable-libx264 --enable-libxvid --enable-shared --enable-gpl --enable-postproc --enable-nonfree --enable-avfilter --enable-pthreads
# make
# make install
# cd ..
修改/etc/ld.so.conf如下:
include ld.so.conf.d/*.conf
/lib
/lib64
/usr/lib
/usr/lib64
/usr/local/lib
/usr/local/lib64
/usr/local/ffmpeg/lib
# ldconfig
将/usr/local/ffmpeg/bin/ 下的可执行文件复制粘贴在/usr/local/bin/ 下就可以使用了,ffmpeg就安装完成了。
